Overview

The TMUX1511RSVR is a high-performance, 4-channel SPST complementary metal-oxide semiconductor (CMOS) switch designed for high-speed signal routing. It features a wide supply range of 1.5V to 5.5V and maintains a high 3GHz bandwidth, making it suitable for both low-voltage logic and high-frequency data signals. The device supports bidirectional signal paths and includes fail-safe logic that prevents damage when the control pins are driven before the supply voltage is applied.

Why Choose This Part

The TMUX1511RSVR offers excellent signal integrity with a low 2pC charge injection and a channel capacitance of only 2.5pF. Its 4.5 Ohm maximum on-resistance and tight 70mOhm channel-to-channel matching ensure consistent performance across all four circuits. Additionally, the small 2.6mm x 1.8mm UQFN package is ideal for space-constrained PCB layouts requiring multiple independent switch channels.

Applications

High-Speed Signal Routing
Utilize the 3GHz bandwidth to switch high-speed interfaces such as JTAG, SPI, and GPIO signals without significant signal degradation.
Battery-Powered Systems
Benefit from the low 37uA typical operating current and ultra-low leakage for power-sensitive portable electronics.
Signal Level Translation
The 1.8V logic compatibility allows the switch to interface directly with low-voltage microcontrollers while managing higher voltage signal paths.
Input Protection
Use the powered-off protection feature to isolate downstream components from signals up to 3.6V when the switch is unpowered.

Getting Started

When designing with the TMUX1511RSVR, ensure the decoupling capacitor is placed close to the VDD pin to minimize noise. Evaluation can be performed using generic UQFN-16 breakout boards or TI's TMUX evaluation modules if available for this specific footprint. Pay close attention to the 0.4mm pin pitch during PCB assembly to avoid solder bridging between the 16 pins.
